TACK-FASTENED BUTTON.

p Y Specification of Letters Patent.

Patented J une 20, 1916.

Application let May 19, 1913. Serial No. 768,530.

To all whom t may concern:

Be it known that I, GEORGE A. KING, a citizen of the United States,residing at Waterbury, in the county of New Haven and State ofConnecticut, have invented a certain new and useful Improvement inTack-Fastened Buttons, of which the following is a full, clear, andexact description.

This invention relates to that class of tack-fastened Ibuttons in whichthe tack itself is permanently applied to the button, and the buttonattached or set by clenching the tack point in some sort of receivingmedium.

The invention consists of a tack-fastened button, having a hubbed back,and a cap closed down over the back, the hubbed back and the capconstituting the button-head, and a tack arranged within the button-headand between the hubbed back and the cap before the cap is closed downupon the hubbed back, said tack having an extended flat head resting onthe back and its upper portion supporting the Cap, and its pointprojectingJ through the bottom of the hub in such way as to prevent therelative independent turning of the tack and the button-head, and in aposition and to an extent to enable such point to be passed through agarment and clenched on or in a suitable washer, as I will proceed nowto explain and finally claim.

In the accompanying drawings illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure 1 is across-section of the cap. Fig. 2 is an elevation of the tack. Fig. 3 isa longitudinal section of the hubbed back. Fig. 4 is a plan view of oneform of washer, and Fig. 5 is a cross-section of the same. Fig. 6 is asectional elevation of the parts of Figs. 1, 2 and 3 assembled in afinished button. Fig. 7 shows the button of Fig. 6 attached to a pieceof fabric. Fig. 8 is a longitudinal section of a modified form ofbutton. Fig. 9 is a cross-section of a modified form of washer.

The cap or front 1 may be of any usual metal, and construction. The tack2 has a laterally extended flat head 3, and an angular pointed shank 4.The back of the button comprises the flanged back 5 and the hub 6, thelatter made with a hole 7,- which l may b e preformed and of lessdiameter than the tacks shank and thereafter appropriately enlarged andshaped to hug the shank of the tack, by driving the tack through it,thereby positioning the tack in the back of the button and restrainingit and the button-head from independent turning or aXial movement. Thesethree parts are assembled as indicated in Fig. 6, with the bottom of thehead of the tack resting on the back of the button and its fiat top orface supporting the cap l, which is closed down upon the back. Such abutton is applied to a garment, 'which may be represented at 8, by

placing the button on one side of the garmenty and forcing the point ofits tack through the garment and through the hole 9 in the washer l0,and clenching the point of the tack as indicated at 11.

If for any reason it be advisable to conceal the clenched end of thetack, a hollow washer, such as shown at l2, in Fig. 9, may be used. Thiswasher may be made in any suitable way, as by folding a piece of metalupon itself, or using a covered washer, or counter-boring a solid pieceof metal; the illustration in Fig. 9 being suggestive rather thanillustrative of any particular co11struction.

As shown in Fig. 8, the hub may be constricted at 13, so as to form asmall waist and a relatively large base 14, both of which features aredesirable in some classes of work.

In the preferred construction, a hole of smaller diameter than thelarger diameter of the shank of the tack is first made in the bottom ofthe hub of the button, as indi-- cated at 7 in Fig. 3, and then thepoint of the tack is driven through the hole, thereby enlarging the holeand frictionally holding the tack in position and preventing it and thebutton-head from turning independently. The closing in of the front orcap of the button completes the retention of the tack in position. Thehead of the tack takes the place of the ordinary flat filler or anvil,and distributes the `pressure in set ting the button over the front orcap, so that such front or cap is not materially marred in the act ofsetting the button. Obviously, it is desirable that the button back andthe head of the tack should be' so protom ofthe hub vand held therein solas tov prevent relative turning of the tack and hubbed back, and a capclosed dovvn over the back and supported by the head of the tack.

2. A tack fastened button, having a hubbed back, a tack provided with alaterally extended flat head arranged' Within the hubbed back andresting upon the back and having a point projecting through the bottomof the hub in angular engagement therewith so as to prevent relativeturning of the tack and hubbed back, and a cap closed'down over thebackjand supported Y b v the head of the tack.

3. A tack fastened button,l having a hubbed back, a tack provided witha'laterally extended flat head arranged within the hubbed back andresting upon the back and having a point projecting through the botf tomof the hub andy held therein so -as to prevent relative turning'of thetack and hubbed back, and a cap closed down over the vback and supportedlby the head V'of the tack, the hub constricted laterally to produce varelatively large base for engagement withV the material to which thebutton is applied.

4L. A tack fastened button, having a -hubbed' back, a tack provided witha laterally extended flat head arranged Within the hubbed back andresting upon the back and having a point projecting through the bottoni'of the hub and held therein so as to prevent lateral. turning `01'?the'tack and hubbed back, anda cap'closed down over the back andsupported by the head of the tack, combined With a Washer engaged by theupset point, of the tack'in setting the button.
